The literature shows contradictory data respect to energy change happening inside biomass sample during thermal treatment. Different DTA/TG studies in the present literature show either exothermic or endothermic reactions happening inside of biomass samples. For being able to correlate the temperature profiles with the actual energy change taking place inside of biomass particles respect to the reactions happening at its surface, inside particle gas sampling measurement has been proposed.

My research provides better understanding of pyrolysis kinetics, through the correlation of pyrolysis gas composition with reaction heat. To our knowledge, this is the first time gas sampling measurements inside of a sample have been made.

This innovative research comes as support for extensive kinetic study of biomass decomposition during non-oxidant thermal treatments.
